Origin and maintenance of chemical diversity in a species-rich tropical tree lineage
Plant secondary metabolites play important ecological and evolutionary roles, most notably in the deterrence of natural enemies. The classical theory explaining the evolution of plant chemical diversity is that new defences arise through a pairwise co-evolutionary arms race between plants and their...

Plant secondary metabolites play important ecological and evolutionary roles, most notably in the deterrence of natural enemies.
